What is radial mononeuropathy?

Radial neuropathies result from injury due to penetrating wounds or fractures of the arm, compression, or ischemia. Most commonly, they present with a wrist drop. The pattern of clinical involvement is dependent on the level of injury.

Radial neuropathies can occur from surgical procedures such as humeral nailing performed to stabilize an acute humeral fracture.

The terms Saturday night palsy and honeymooner's palsy refer to the concept of placing one's arm over another chair, with the resultant pressure causing injury to the radial nerve.
